Sendyne SFPGFD Ground Fault Detection, High Voltage and Current Measurement IC and Module

The Sendyne SFPGFD IC and Module is the first single IC and module capable of performing ground fault detection / isolation monitoring while simultaneously providing accurate current, high voltage and temperature measurements.

― Performs ground fault detection / isolation monitoring
― Detects all sources of leakage
― Applies deep filtering & averaging on the measured data, resulting in a high level of noise rejection
― Measures ±450 V continuous and ±650 V momentary overvoltage (extendable)
― Built-in calibration for voltage measurements
― Measures 300 A continuous, 1500 A peak
― Current measurement / Coulomb counting accuracy of 0.25% from –40 °C to +125 °C
― Isolated front end for “high” or “low” side current sensing
― Built-in compensation for resistance dependence of the shunt on temperature from
― Temperature reporting in degrees Celsius
― Standard LIN interface, other protocol available
― AEC-Q100 qualified IC
― Low power consumption

― HEV and EV Power systems monitoring
― Charging stations
― Battery monitoring, industrial, railroad and utility-scale storage
